Is sebaceous carcinoma rare?

Sebaceous carcinoma is a rare type of cancer that begins in an oil gland in your skin. Sebaceous carcinoma most often affects the eyelids.

How common is sebaceous gland carcinoma?

So this type of cancer can be diagnosed anywhere in the body. But the most common site is the upper eyelid. Sebaceous gland carcinoma is very rare. Just over 700 people were diagnosed with it in England between 1999 and 2008.

How serious is sebaceous carcinoma?

Sebaceous carcinoma is an aggressive and potentially dangerous tumour that can lead to significant morbidity and mortality. The overall mortality rate is 5–10% because of inherent tumour factors, or delayed diagnosis and treatment.

How fast does sebaceous carcinoma grow?

In general, extraocular sebaceous carcinoma is less aggressive than ocular sebaceous carcinoma [4]. However, some authors have reported that extraocular tumors preferentially show a rapid growth. This is especially true in elderly women [6]. In the present patient, the lesion was rapidly growing in just 2 weeks.

How aggressive is sebaceous carcinoma?

Sebaceous carcinoma is a rare and aggressive malignant cutaneous cancer that arises from the sebaceous gland epithelium. This type of cancer typically presents in the periocular area and is rarely expressed in the extraocular space. The estimated overall incidence rate is one to two per million people per year.

Is sebaceous carcinoma fatal?

Sebaceous carcinoma is a rare, highly malignant, and potentially lethal tumor of the skin, which most commonly occurs in the eyelid. The neoplasm arises from sebaceous glands, such as those of the meibomian glands in the tarsus, the Zeis glands of the eyelashes, the caruncle, and the skin of the eyebrow.

What are the signs and symptoms of sebaceous gland carcinoma?

Sebaceous carcinoma: Signs and symptoms

  • Slowly growing, often yellowish lump on the eyelid that feels firm, deep, and painless.
  • Thickening of an eyelid, where lid meets lash.

Is sebaceous carcinoma hereditary?

Introduction: Muir–Torre syndrome (MTS) is a hereditary cancer syndrome defined by the coexistence of one or more cutaneous sebaceous neoplasms and internal malignancy. Germline mutations of DNA mismatch repair (MMR) gene are characteristically found in these patients, most often a mutation in the MSH-2 gene.

Is sebaceous adenoma malignant?

Sebaceous adenoma is a rare, benign tumor of sebaceous glands. Approximately 70% of lesions develop on the head and face, with the nose and cheek most commonly affected; 30% of lesions occur on the neck, trunk and extremities.

Can sebaceous adenomas become cancerous?

Significance. Sebaceous adenomas, in isolation, are not significant; however, they may be associated with Muir-Torre syndrome, a genetic condition that predisposes individuals to cancer. It is also linked to hereditary nonpolyposis colorectal cancer (Lynch syndrome).

Are all cancers carcinomas?

Not all cancers are carcinoma. Other types of cancer that aren’t carcinomas invade the body in different ways. Those cancers begin in other types of tissue, such as: Bone.
